NASA scientists say soot, mostly from diesel engines, is causing as much as a quarter of all observed global warming by reducing the ability of snow and ice to reflect sunlight. Their findings on how soot affects reflective ability, known as albedo, raise new questions about human-caused climate change from the Arctic to the Alps.
